As for possessive pronouns like “its,” “whose” and “hers,” all you can do is remember that possession is incorporated into the word, so there’s no need for an apostrophe.

Possessive pronouns. In school, we heard over and over that a possessive takes an apostrophe. But the lesson about possessive pronouns doesn’t seem to get as much play.

This is because possessive pronouns don't have apostrophes, even the ones with an s. Properly, it's his, hers, yours, theirs, whose, though many people get those wrong.

Possessive pronouns: They show possession or ownership of something or someone and are used in place of nouns. They include mine, yours, his, hers and its: John left with Ade’s bag.

CAN the possessive pronoun 'whose' be used after a thing? If so, could you please give me a few examples? I am puzzled as I thought 'whose' should be used after a pronoun, a person or animal.
